(54)	METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING POSITIONING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM

(57) A method of processing a positioning reference signal comprises transmitting, to a narrow-band user equipment, NB UE, NB positioning reference signal, PRS, configuration information configured for the NB UE. The NB PRS configuration information comprises an NB PRS bitmap indicating a pattern for selecting NB PRS subframes, wherein each NB PRS subframe is a subframe for transmitting an NB PRS for positioning the NB UE, and wherein the NB PRS bitmap is configured to indicate a plurality of non-consecutive NB PRS subframes in each radio frame of one or more radio frames corresponding to one repetition of the NB PRS bitmap. The method further comprises based on a plurality of repetitions of the NB PRS bitmap, transmitting, to the NB UE, a first NB PRS mapped in first NB PRS subframes of an NB PRS reference cell, transmitting, to the NB UE, a second NB PRS mapped in second NB PRS subframes of an NB PRS neighbor cell and receiving, from the NB UE, at least one signal indicating at least one reference signal time difference, RSTD, measurement based on the transmitted first NB PRS and the transmitted second NB PRS.
